pH Meter – pHSense
The pHSense range of online pH meters from Pi utilize the very latest and best pH sensors available in the world today for measuring the online pH of any aqueous solution.
They are patented gel filled sensors with integral reference which uses no reagents, are extremely stable, and have reduced maintenance and reduced whole life costs. The junction, usually the source of error with current pH sensor technology is made from an electrochemically active solid resulting in a more robust pH sensor.
Online pH meters and pH controllers are one of the most common analyzers in use today in water treatment and process plants and yet online pH meters cause continual problems for their operators. What is needed is a stable, reliable, online pH meter for a reasonable cost. That is exactly what you get with the pHSense.
The pHSense sensors and flow cells are available with different controllers giving you the same great performance with different communication, display, and control options. With the pHSense range of online pH meters, you get everything that you need – and nothing that you don’t.
